For example, in the present embodiment, the user terminal 100 automatically determines outdoor / indoor and performs transfer setting / cancellation, but the determination target is not limited to outdoor / indoor, and a predetermined area It is also possible to perform transfer setting / cancellation by determining whether it is inside or outside. That is, the determination of indoor / outdoor can be more generally rephrased as the determination within the predetermined area / outside the predetermined area.

(System configuration)
FIG. 1 shows a system configuration according to the embodiment of the present invention. As shown in FIG. 1, the system according to the present embodiment has a transfer source telephone network 500 and a transfer destination telephone network 600. The transfer source telephone network 500 is, for example, a fixed telephone network using a 0ABJ number. In this embodiment, since the telephone network is a transfer source telephone network, it is referred to as “transfer source telephone network 500”. The transfer source telephone network 500 has a call control system 400 that performs various call controls such as call connection and call transfer. The call control system 400 also includes a transfer setting server 410 that executes transfer setting.

  The transfer destination telephone network 600 is, for example, a VoIP network, a mobile telephone network, or the like that enables a call by a mobile terminal such as a smartphone. In the present embodiment, since the telephone network is the telephone network of the forwarding destination, this is referred to as the "destination telephone network 600."

  The transfer source telephone network 500 and the transfer destination telephone network 600 are interconnected. The telephone network consisting of the transfer source telephone network 500 and the transfer destination telephone network 600 is an example of the “telephone network that performs call transfer”.

  In FIG. 1, a calling terminal 300 and an indoor terminal 200 connected to a transfer source telephone network 500 are shown. Also, the user terminal 100 is shown. As shown in FIG. 1, the indoor terminal 200 is installed in a building such as a house (indoor). The indoor terminal 200 is a general fixed telephone, but is not limited thereto.

  The user terminal 100 has a wireless LAN function, is connected to the transfer destination telephone network 600 wirelessly (or by wire), and is a general smartphone that can make and receive calls via the transfer destination telephone network 600. It is assumed that However, using a smartphone as the user terminal 100 is merely an example, and it is also possible to use, for example, a PC, a tablet, or the like as the user terminal 100.

  Further, the user terminal 100 can access the transfer setting server 410 via the Internet to execute transfer setting and the like.

  In the present embodiment, the user receives an incoming call for the telephone number of the indoor terminal 200 at the indoor terminal 200 when the user is indoors, and the user receives an incoming call for the telephone number of the indoor terminal 200 when the user is outdoor. It can be received by the terminal 100. In order to perform such reception, when the user terminal 100 in the present embodiment detects that he or she has gone from indoor to outdoor, the user terminal 100 automatically implements the transfer setting for the transfer setting server 410, and the user terminal 100 performs the transfer setting. When it is detected that the vehicle has entered indoor from outside, the transfer setting server 410 automatically performs transfer cancellation.

  In FIG. 2, the block diagram of the user terminal 100 is shown. As shown in FIG. 2, the user terminal 100 includes a transfer control execution determination unit 101, a transfer control execution unit 102, a telephone function unit 103, and a wireless LAN function unit 104. FIG. 2 shows only the functional units particularly related to the embodiment of the present invention in the user terminal 100. Further, the functional configuration shown in FIG. 2 is merely an example. As long as the operation according to the present embodiment can be performed, the names of the function classifications and the function parts may be arbitrary.

  The transfer control execution determining unit 101 in the user terminal 100 determines whether the user terminal 100 is located indoors or outdoors, and performs transfer setting or transfer cancellation on the transfer setting server 410 based on the determination result. Decide whether or not.

  The transfer control execution unit 102 executes transfer setting / transfer cancellation on the transfer setting server 410 according to the determination (transfer setting execution or transfer cancellation execution) by the transfer control execution determination unit 101.

  The telephone function unit 103 is a functional unit for connecting to the transfer destination telephone network 600 to make a call. The telephone function unit 103 may be a mobile phone function provided in advance in the user terminal 100, or may be a function unit realized by installing a VoIP application in the user terminal 100. In any case, the telephone function unit 103 according to the present embodiment includes a function of connecting to a wireless base station by 3G / LTE / Wimax or the like and connecting to the Internet via a mobile telephone network or the like.

  The wireless LAN function unit 104 is a functional unit that connects to a wireless LAN access point via a wireless LAN and performs communication in the wireless LAN.

  The user terminal 100 according to the present embodiment executes the transfer control execution unit 102 and the transfer control execution in the present embodiment on a computer (smartphone etc.) having a wireless access function such as 3G / LTE / Wimax and the wireless LAN function unit 104. This can be realized by executing a program including the processing content of the determination unit 101. That is, the functions of the user terminal 100 correspond to the processing performed by the transfer control execution unit 102 and the transfer control execution determination unit 101 using hardware resources such as a CPU, a memory, and a hard disk built in the computer. It can be realized by executing a program. In addition, the program can be recorded in a computer readable recording medium (portable memory or the like), and can be stored or distributed. Moreover, it is also possible to provide the above program through a network such as the Internet or e-mail.

(About indoor / outdoor judgment)
The transfer control execution determining unit 101 of the user terminal 100 in the present embodiment uses the wireless LAN function to determine whether the user terminal 100 is located indoors or outdoors. Specifically, it is as follows.

  In the present embodiment, a wireless LAN access point (a wireless LAN router or the like) is installed indoors where the indoor terminal 200 is installed. The user terminal 100 is automatically connected to the wireless LAN by the wireless LAN function unit 104 when the intensity of the radio wave received from the wireless LAN access point is equal to or more than a predetermined value. By using a wireless LAN as an access line, for example, use of a web service can be performed via the Internet.

  When the user terminal 101 is connected to the indoor wireless LAN, the possibility that the user terminal 101 is located indoors is high. Therefore, when the user terminal 101 is connected to the indoor wireless LAN, the transfer control execution determining unit 101 in the present embodiment determines that the user terminal 101 is located indoors and is not connected. It is determined that the user terminal 101 is located outdoors. However, as described later, as for outdoor determination, determination other than that it is not connected to the indoor wireless LAN is also possible.

  Since many radio waves of the wireless LAN are scattered, the transfer control execution determination unit 101 determines whether or not the indoor terminal 200 is connected to the indoor wireless LAN in which the indoor terminal 200 is installed, when connected to the wireless LAN. There is a need. In the present embodiment, this determination is performed using an SSID (Service Set Identifier, an identification name of an access point).

  That is, for the transfer control execution determination unit 101, the SSID of the indoor wireless LAN is registered in advance. Then, when wireless LAN connection is made by the wireless LAN function unit 104, the transfer control execution determination unit 101 acquires the SSID of the connected wireless LAN from the wireless LAN function unit 104, and registers it with this SSID. It compares with existing SSID, and when these match, it is judged that it is connected to the indoor wireless LAN.

  When the wireless LAN connection is made by the wireless LAN function unit 104 but the SSID of the connected wireless LAN and the registered SSID are different, the transfer control execution determination unit 101 determines that the user terminal 100 is not located indoors It can be judged.

  The use of the SSID is merely an example, and other information may be used to determine the presence / absence of indoor wireless LAN connection. As an example, the determination may be made using a password used when connecting to a wireless LAN. Alternatively, determination may be made using both the SSID and the password.

  Also, performing indoor / outdoor determination using the wireless LAN function is merely an example, and outdoor / indoor may be determined using other methods.

  For example, when the user terminal 100 has a GPS function, it is also possible to determine indoor / outdoor using the GPS function. In this case, the transfer control execution determination unit 101 registers in advance a predetermined position (such as a center position) indoors and a distance threshold. Then, the transfer control execution determination unit 101 calculates the distance between the current position of the user terminal 100 acquired by the GPS function and the registered predetermined position, and determines that the position is indoors if the distance is equal to or less than the threshold. If the distance is greater than the threshold, it can be determined that the user is outdoors.

  When the user terminal 100 is connected to the transfer destination telephone network 100 by wire communication by the telephone function unit 101 or the like, the transfer control execution determination unit 101 of the user terminal 100 transmits the transfer destination telephone network 100 by wire connection of the telephone function unit 101. When it is detected that the terminal is connected, it may be judged as "outside".

(System operation)
Next, the operation of the system having the above-described configuration will be described. In the example described below, indoor / outdoor determination is performed using a wireless LAN function. Also, let the telephone number of the indoor terminal 200 be a telephone number A, and let the telephone number of the user terminal 100 be a telephone number B.

  Further, in the following example, it is assumed that the telephone function unit 103 in the user terminal 100 is already provided, and that the telephone function unit 103 is in a state capable of making a call using the transfer destination telephone network 600. That is, when the telephone function unit 103 is realized by a VoIP application, it is assumed that the VoIP application has already been installed and activated. However, the VoIP application may have the functions of the transfer control execution determination unit 101 and the transfer control execution unit 102 in addition to the telephone function, in which case, the telephone function unit 103 executes transfer control in step S101 below. A determination unit 101 and a transfer control execution unit 102 are provided in the user terminal 100.

<Preparation procedure by user>
First, the preparation procedure by the user will be described with reference to the flowchart of FIG. In step S101, when the user operates the user terminal 100, for example, the website designated by the service provider is accessed, and the functions of the transfer control execution determination unit 101 and the transfer control execution unit 102 are accessed from the website. The application (program) to be included is downloaded, and the application is installed in the user terminal 100 and activated.

  When step S101 is completed, the transfer control execution determination unit 101 displays an input screen of the wireless LAN SSID on the user terminal 100 (for example, on the touch panel of the user terminal 100). In step S102, the user inputs the SSID of the wireless LAN used indoors from the input screen. The input SSID is stored in storage means such as a memory in the user terminal 100.

  In addition to the manual input as described above, the transfer control execution determination unit 101 displays the SSID of the wireless LAN capturing the radio wave on the screen, and the user selects the SSID of the indoor wireless LAN. The SSID of the wireless LAN used indoors may be stored in the storage means.

  In the user terminal 100, an input screen for inputting information for transfer setting is displayed by the transfer control execution determination unit 101, and in step S103, the user inputs information for transfer setting from the input screen. Do. The information input here is, for example, address information (IP address or FQDN) of the transfer setting server 410 as an access destination for transfer setting / cancellation, an ID and password for entering the transfer setting server 410, and a telephone of a transfer source. The number A is the transfer destination telephone number B.

  The information input as described above is stored in the storage unit of the user terminal 100, and is used in transfer setting / cancellation.

  Note that the address information of the transfer setting server 410, the password / ID, and the like may be included in the application to be downloaded in step S101, and the input may not be performed here.

<Operation when moving from indoor to outdoor>
Next, with reference to FIG. 4, an operation of the system when the user terminal 100 moves from indoor to outdoor will be described.

  As a premise of the operation illustrated in FIG. 4, the user terminal 100 is initially located indoors, transfer setting is not performed, and the transfer control execution determination unit 101 holds information indicating that transfer setting is not performed. It shall be. Based on the information indicating the state, the transfer control execution determination unit 101 recognizes that the transfer setting has not been made.

  The transfer control execution determination unit 101 of the user terminal 100 periodically determines whether the user terminal 100 is located indoors or outdoors. While the user terminal 100 is connected to the indoor wireless LAN, the transfer control execution determination unit 101 determines that the user terminal 100 is located indoors, and does not execute the process of transfer setting. More specifically, the determination here is that the transfer control execution determination unit 101 detects that “the user terminal 100 is located indoors” and “the transfer setting has not been made”. It may be determined that the process is not performed.

  In step S201, the transfer control execution determination unit 101 of the user terminal 100 detects that the user terminal 100 is not connected to the indoor wireless LAN. Thereby, the transfer control execution determination unit 101 determines that the user terminal 100 is located outdoors. In the state of "not connected to the indoor wireless LAN", in addition to the case where the wireless LAN is not connected at all, the wireless LAN is connected but the SSID of the wireless LAN is the SSID of the indoor wireless LAN Including different cases.

  The transfer control execution determination unit 101 detects that it is not connected to the indoor wireless LAN (detects that it is outdoors), and determines that transfer setting has not been made at the current point of time, to the transfer setting server 410. Then, it decides to execute the transfer setting, and instructs the transfer control execution unit 102 to execute the transfer setting.

  Further, the transfer control execution determination unit 101 determines that “connected to a wireless access line such as 3G / LTE / Wimax, or connected to a wireless LAN other than the indoor wireless LAN” as “outside”. Under the condition, if it is determined that "outdoor" is determined based on this condition, and if "the transfer setting is not made at the current time", it is decided to execute the transfer setting, and the transfer control execution unit 102 is instructed to execute the transfer setting. You may do it. In addition, “connected to a wireless access circuit such as 3G / LTE / Wimax, or connected to a wireless LAN other than an indoor wireless LAN” by the function of the user terminal 100, and “an indoor wireless LAN In the case where "connect to" may occur simultaneously, the condition that "does not be connected to the indoor wireless LAN" may be added to the "outdoor" condition described above as the "outdoor" condition.

  With regard to the above example, the user terminal 100 is wirelessly connected by being in a state of “connected to a wireless access line such as 3G / LTE / Wimax or connected to a wireless LAN other than the indoor wireless LAN”. It is possible to connect to the Internet via an access line or the like and connect to the transfer setting server 410.

  However, it is also possible to determine the execution of the transfer setting by “not being connected to the indoor wireless LAN” without using this condition. In this case, the transfer control execution unit 102 performs “3G / 3”. If it is in the state of “connect to a wireless access line such as LTE / Wimax or connect to a wireless LAN other than the indoor wireless LAN”, the transfer setting is executed, and if this state is not reached, the transfer setting is not executed. Perform the operation.

  At the time of step S202, the user terminal 100 is connected to a wireless access line such as 3G / LTE / Wimax, or connected to a wireless LAN other than the indoor wireless LAN, so the user terminal 100 is connected to the Internet It can be connected to

  In step S202, the transfer control execution unit 102 of the user terminal 100 accesses the transfer setting server 410 using the ID / password via the Internet, and transfers transfer setting information (transfer source: telephone number A, transfer destination: telephone number B). Is sent to the transfer setting server 410 to carry out the transfer setting. Note that the transfer setting information here is merely an example, and may include more detailed setting information (transfer time zone, transfer upon no response, transfer upon busy, etc.).

  In step S203, with the function of the transfer setting server 410, in the call control system 400, transfer setting is performed to transfer an incoming signal addressed to the telephone number A (indoor terminal 200) to the telephone number B (user terminal 100). When the transfer setting is made, the transfer control execution determination unit 101 stores state information indicating that the transfer setting is made in the storage unit.

  Thereafter, the calling terminal 300 makes a call with the telephone number A (indoor terminal 200) as the destination. In step S 204, an incoming signal relating to the outgoing call is sent to the call control system 400.

  Assuming that the transfer setting is not made, the incoming signal reaches the indoor terminal 200 as shown by the dotted line in FIG. 4, but in the present example, since the above transfer setting is made, the transfer process is performed in step S205. The incoming signal is forwarded to the telephone number B (user terminal 100). Thus, the incoming call signal is transferred to the transfer destination telephone network 600 (step S206), and transmitted from the transfer destination telephone network 600 to the user terminal 100 (step S207). The user terminal 100 can receive an incoming signal addressed to the telephone number A (indoor terminal 200) transmitted from the calling terminal 300, and can make a call with the calling terminal 300.

<Operation when moving from outdoor to indoor>
Next, with reference to FIG. 5, an operation of the system in the case where the user terminal 100 moves from outdoors to indoors will be described.

  As a premise of the operation illustrated in FIG. 5, the user terminal 100 is initially located outdoors, the transfer setting is performed for the transfer setting server 410, and the transfer control execution determination unit 101 is configured to perform the transfer setting. Holds information indicating. Based on the information indicating the state, the transfer control execution determination unit 101 recognizes that the transfer setting is made.

  As described above, the transfer control execution determination unit 101 of the user terminal 100 periodically determines whether the user terminal 100 is located indoors or outdoors. While the user terminal 100 is not connected to the indoor wireless LAN, the transfer control execution determination unit 101 determines that the user terminal 100 is located outdoors (or not located indoors), and the transfer release is performed. Do not execute the process.

  In step S301, the transfer control execution determination unit 101 determines that the user terminal 100 is located indoors by detecting that the user terminal 100 is connected to the indoor wireless LAN. "Connecting to an indoor wireless LAN" means connecting to a wireless LAN and matching the SSID of the wireless LAN with a previously set SSID.

  The transfer control execution determination unit 101 that has detected connection to the indoor wireless LAN and has determined that transfer setting has been made at this point determines that transfer release is to be performed, and performs transfer release. Are instructed to the transfer control execution unit 102.

  In step S302, the transfer control execution unit 102 of the user terminal 100 accesses the transfer setting server 410 using the ID / password via the Internet, and transmits transfer cancellation information to the transfer setting server 410, thereby canceling the transfer. carry out. The transfer cancellation information includes information instructing cancellation of the transfer setting set as “transfer source: telephone number A, transfer destination: telephone number B”. Note that the information specifying "transfer setting set as" transfer source: telephone number A, transfer destination: telephone number B "" may be an ID for identifying this setting, or "transfer source: telephone number A, Transfer destination: It may be information including the telephone number B ".

  In step S303, the call control system 400 cancels the transfer setting of transferring an incoming signal addressed to the telephone number A (indoor terminal 200) to the telephone number B (user terminal 100). Further, the transfer control execution determination unit 101 of the user terminal 100 holds information indicating that transfer setting has not been made.

  Thereafter, the calling terminal 300 makes a call with the telephone number A (indoor terminal 200) as the destination. In step S304, an incoming signal for the transmission is sent to the call control system 400. Since the transfer setting is canceled at this point, the incoming signal reaches the indoor terminal 200 in step S305. Thus, the user can receive an incoming call addressed to the telephone number A (indoor terminal 200) transmitted from the calling terminal 300 at the indoor terminal 200.

<On the occasion of indoor / outdoor judgment>
In the above example, the transfer control execution determination unit 101 periodically determines indoor / outdoor, but the transfer control execution determination unit 101 is not regular and detects indoors when a predetermined trigger is detected. It is also possible to make an outdoor determination. The predetermined trigger is, for example, a state where the user terminal 100 is connected to the mobile telephone network (here, the transfer destination telephone network 600 here) by 3G / LTE from the state where the user terminal 100 is connected to the wireless LAN. In addition, it is also a predetermined trigger that the user terminal 100 is connected to the wireless LAN from the state where it is connected to the mobile phone network by 3G / LTE.

  Further, in the above example, the transfer control execution determination unit 101 manages transfer setting / cancellation by indoor / outdoor determination performed periodically by managing information indicating whether transfer setting is made or not. It is also possible to adopt a method in which information is not managed that indicates whether or not transfer settings have been made although it is avoided that repetition is performed. In this case, if the indoor / outdoor determination result performed at a certain time is the same as the determination result performed immediately before that in the indoor / outdoor determination performed periodically, the transfer setting / cancellation is not performed, When it is different from the determination result performed immediately before, it is determined to execute transfer setting / cancellation based on the determination result at that time.

  For example, when it is determined that the user terminal 100 has moved from indoor to outdoor when it is determined to be indoor by the first determination and determined to be outdoor by the next determination, the process of transfer setting is performed, and the next determination is made. When it is determined to be outside, the process of transfer setting / cancellation is not performed.

  When managing information indicating whether transfer setting has been made, determining that the user terminal 100 has moved from indoor to outdoor in a state where transfer setting has not been made determines that the user terminal 100 has moved from indoor to outdoor. It is an example.

  Also, for example, when it is determined that the user terminal 100 has moved from indoor to indoor when it is determined to be outdoor in the first determination and determined to be indoor in the next determination, the transfer cancellation processing is performed, and the next If it is determined that the room is indoors, the process of transfer cancellation / setting is not performed.

  When managing information indicating whether transfer setting is performed, it is determined that the user terminal 100 has moved from outdoor to indoor when it is determined that the user terminal 100 is indoors in the state where the transfer setting is performed. It is an example.

(Modification)
In the system shown in FIG. 1, it is assumed that the transfer source telephone network 500 and the transfer destination telephone network 600 are different service providers (for example, a fixed telephone carrier and a mobile telephone carrier). A service for transferring a number to another telephone number can be provided not only among such a plurality of operators but also within one service provider or within a corporate network.

  As an example, it is possible to assume a service for transferring a call addressed to an extension telephone number (outside telephone number) to an outside telephone number (extension telephone number). The technology according to the present invention is also applicable to the forwarding service provided within such a single service provider (or within the enterprise network). Hereinafter, an example in which the technology according to the present invention is applied to a transfer service assumed to be implemented within one service provider will be described as a modified example. The following description focuses on differences from the examples described above. Further, the example described above is called a basic example for convenience.

<System configuration>
FIG. 6 is a system configuration diagram in a modification. As shown in FIG. 6, the system according to the modification has a telephone network 800. The telephone network 800 includes a call control system 700, which performs various call controls such as call connection and call transfer. In a variation, SIP is used as a call control protocol, but this is an example, and protocols other than SIP may be used. The call control system 700 also includes a transfer setup server 710 for performing transfer setup. Similar to the basic example, the user terminal 100 can access the transfer setting server 710 via the Internet to perform transfer setting / cancellation and the like.

  In the modification, the call control system 700 includes the telephone number of the source and the telephone number of the transfer source (the telephone number of the destination at the time of origination from the source) in the incoming signal when the call is transferred. It is possible to transmit an incoming signal including a number to the transfer destination terminal.

  Further, when receiving the transferred incoming call, the user terminal 100 displays the telephone number of the calling source and the telephone number of the forwarding source as the incoming call history, and transmits the telephone number of the forwarding source by a user operation of the call button or the like. It is possible to make a call back to the originator.

  In FIG. 7, the block diagram of the user terminal 100 in a modification is shown. As shown in FIG. 7, the user terminal 100 of the modification differs from the user terminal 100 in the basic example in that the incoming call history processing unit 105 is included. The functional units other than the incoming call history processing unit 105 are the same as in the basic example. For example, the incoming call history processing unit 105 may be added as an additional function to an application (program) corresponding to the transfer control execution determination unit 101 and the transfer control execution unit 102, or the incoming call history processing unit 105 may be an independent application (program Or the function of the incoming call history processing unit 105 may be provided as part of a VoIP application.

<Operation when moving from indoor to outdoor>
Next, with reference to FIG. 8, an operation of a system according to a modification in a case where the user terminal 100 moves from indoor to outdoor will be described. In the following, the telephone number of the calling terminal 300 is taken as the telephone number C. Further, the telephone function unit 103 of the user terminal 100 is set to be able to make a call by using the telephone number A which is not the telephone number B of the user terminal 100 as the caller. As an example, in the telephone function unit 103, account information of the telephone number A is set as account information for using the call control system 700. The premise of the other operations, the indoor / outdoor determination, the implementation determination of the transfer setting, and the implementation contents of the transfer configuration are the same as in the basic example.

  In step S401, the transfer control execution determination unit 101 determines that the user terminal 100 is located outdoors, and in step S402, the transfer control execution unit 102 transmits the transfer setting information to the transfer setting server 710. Implement transfer settings. In step S403, the call control system 700 sets transfer.

  Thereafter, the calling terminal 300 makes a call with the telephone number A (indoor terminal 200) as the destination. In step S404, an incoming signal (source telephone number = telephone number C) for the transmission is sent to the call control system 700.

  In step S405, transfer processing is performed, and the incoming signal is transferred to the telephone number B (user terminal 100). The incoming signal reaches the user terminal 100 (step S406). Thus, user terminal 100 can receive an incoming signal addressed to telephone number A (indoor terminal 200) transmitted from transmitting terminal 300, and can make a call with transmitting terminal 300.

  In the present modification, in step S406, the telephone function unit 103 of the user terminal 100 receives the transferred incoming signal. Specifically, this incoming signal is an INVITE message. For example, the From header of the INVITE message includes the telephone number C of the source, and the route header, the via header, etc. includes the (original destination) telephone number A of the transfer source.

  When an incoming call arrives, the incoming call history processing unit 105 acquires an incoming call signal (INVITE message) from the telephone function unit 103, and a telephone number is included in a predetermined header (for example, route header, via header) on a transfer route. It is determined that the incoming signal is a transferred signal, and the telephone number (in this example, the telephone number A) included in the predetermined header is acquired as the transfer source telephone number. Further, the incoming call history processing unit 105 acquires the telephone number of the caller (in this example, the telephone number C), and stores the incoming call history including the telephone number A and the telephone number C in the storage unit. Here, the telephone number A is stored as a transfer source telephone number, and the telephone number C is stored as a source telephone number.

  Thereafter, it is assumed that the user performs return transmission from the user terminal 100 to the transmission terminal 300. Here, for example, based on an operation on the user terminal 100 by the user, the incoming call history processing unit 105 reads out the incoming call history stored at the time of the above incoming call, and displays the incoming call history on a display (touch panel or the like). On the screen displayed at this time, the telephone number C as the caller's telephone number is displayed as the information on the incoming call history, and the telephone number A as the transferer's telephone number is displayed.

  The user designates, for example, the telephone number C of the caller and instructs the call back. Based on this instruction, the incoming call history processing unit 105 instructs the telephone function unit 103 to make a call to the telephone number C, which uses the telephone number A which is the transfer source telephone number as the transmission source.

  Then, in step S407 in FIG. 8, the telephone function unit 103 makes a call to the telephone number C. The telephone number A is described in the header (example: From header) indicating the originator in the transmission signal (INVITE message) sent out here. The calling signal is transmitted to the calling terminal 300 via the call control system 700 (step S408). For example, the telephone number A is displayed on the transmission terminal 300 as the telephone number of the transmission source. As a result, the user of the calling terminal 300 recognizes that a return call has been received from the destination sent in step S404. As described above, in the modification, even when the transfer setting is made, it is possible to perform return transmission to the source that has made the transfer call by using the transfer source telephone number as the source.

  Note that, even in the case of return transmission of a transfer call, the user terminal 100 can also make a transmission with the telephone number B as a transmission source by setting. In addition, when making a call from the telephone number A as a caller, the user terminal 100 records the telephone number A as a caller telephone number in the call history.

(Summary of the embodiment)
As described above, according to the present embodiment, a user terminal having a function of connecting to a telephone network for call transfer, wherein the user terminal is located in a predetermined area or a predetermined one When it is determined that the user terminal has moved from the inside of the predetermined area to the outside of the predetermined area by the judging means for judging whether or not the user terminal is located outside the area of A user terminal is provided which comprises: transfer control means for implementing transfer settings.

  The transfer setting is, for example, a setting for transferring an incoming signal to a terminal installed in the predetermined area to the user terminal.

  When it is determined by the determination unit that the user terminal has moved from the outside of the predetermined area into the predetermined area, the transfer control unit cancels the transfer setting for the telephone network. You may do it.

  The user terminal holds, for example, specific identification information for identifying a wireless LAN used in the predetermined area, and the determination unit identifies the identification information of the wireless LAN to which the user terminal is connected. When it is detected that the identification information matches the specific identification information, it may be determined that the user terminal is located in the predetermined area.

  The determination means periodically executes determination as to whether the user terminal is located within a predetermined area or outside a predetermined area, and the determination result at a certain point in time is outside the predetermined area. If the determination result immediately before is within the predetermined area, it may be determined that the user terminal has moved from within the predetermined area to outside the predetermined area at the time.

  The user terminal holds information indicating whether or not the transfer setting is made, the determination means detects that the transfer setting is not made based on the information, and the user terminal When it is detected that the user terminal is located outside the predetermined area, it may be determined that the user terminal has moved from inside the predetermined area to outside the predetermined area.

  When the user terminal receives an incoming signal relating to transfer from the telephone network, the user terminal stores the source telephone number and the transfer source telephone number included in the incoming signal as an incoming call history, and based on the incoming call history. It is also possible to provide means for executing return transmission by transmitting a transmission signal having the transfer source telephone number as a transmission source to the transmission source telephone number.

  According to this embodiment, it is possible to automatically set transfer settings for the telephone network when transfer is necessary. Thereby, the user can receive an incoming call for transfer related to the destination at the place outside without setting the transfer each time the user goes out. When the user is indoors, the indoor terminal can receive an incoming call addressed to the indoor terminal.
